For fans of ironic timing, Tuesday's tech new couldn't have been more perfect. Apple debuted a 128-GB iPad in the morning, ostensibly in response to the imminent release of Microsoft's Surface Pro, which will go on sale in 64-GB and 128-GB varieties on February 9. Within hours, Apple's evident intent to compete on storage took a turn, as, almost on cue, reports began circulating that Windows 8 will occupy 45 GB on the Surface Pro's drive, leaving the device's usable storage capacity far short of advertised specs.
